... Your rocket ship will take you to each of the planets, starting with Earth. While on each planet you must save as many humans as you can, but be careful because the Brain Aliens will try to abduct the humans before you can save them. When you save humans, they are teleported to your rocket ship. To escape the planet you must also collect rocket fuel. Once The Giant Brain has been defeated and peace restored to the galaxy, you will return to Earth with your human cargo where they will be freed.
